Flat / Hot Rolled
Flat steel products are obtained by heating semi-finished products with a rectangular cross-section (slab), which are produced by the continuous casting method, to a specific temperature and then rolling them, with thicknesses ranging from 1.40 to 25.40 mm and widths ranging from 700 to 2025 mm, produceed as coil or by cutting/slit-coiling flat steel products from coils.
Triple certified weldable fine-grained structural steel
- Copper content shall be min 0.20% when Cu steel is specified.
- For each reduction of 0.01 percentage point below the specified max C an increase of 0.06 percentage point above the specified max for Mn is permitted up to a max of 1.50% by heat analysis
- Deoxidation method of this products is fully-killed. Minimum aluminium to nitrogen ratio is 2:1.
- The lower limit of 'Si' does not apply in case the content of 'Al' in the steel is min 0.020%.
- Tensile test values apply to "transverse" test pieces
- The impact test is carried out only when specified at the time of enquiry and order and is not carried out for thickness thinner than 6 mm.
- Below 8 mm thickness, according to the item 8.3.1.1 of standart CSA G40.20, elongation value shall differ from the values given in the table

Flat / Plate
Heavy plate products are obtained by rolling semi-finished products with a rectangular cross-section (slab) produced by the continuous casting method to a specific temperature, with thicknesses ranging from 6.00 to 200.00 mm and widths ranging from 1000 to 3600 mm.
